DOOR HANGER.

APPLICATloN AFILED APR. 1s. 1921.

Patented Jan. 31, `1922.

M M w# w m wf @New Af@ nooalnmenagj 'Beitknown thatJoHN J. Rn'xn'o'rH, late a citizen of the United States, residing 'at Chicago, county of Cook, and State; oflllinois, has invented ai new and useful Improvement in Door Hangers, Qwhich the 'following is a specification.

This invention relates to door hangers.

An object of the invention isto .provide a door hanger avoiding the necessity of installing a track diflerentfrom a fiat horizontal tra-ck, and toprovide means in connection with the hanger for distributing the load of the door over a pluralityof antikfriction rollers connected with the doo-r.

Another object of the invention is to provide a door hanger in which the necessity of` providing a guide roller for engaging the track is avoided. f

It is also an object of the present invention to provide anti-friction rollers travel` ling in inclined planes while in contact with the track, so as to avoid a binding effect upon the door. Y j

vWith these and other objects in view, an embodiment of the invent-ion is illustrated in the accompanying drawing, to which reference is madein the following specification, the novel features being pointed out more clearly in the 'appended claims.

In the drawings:

Fig. 1 is a perspective view of the upper portion of a door suspended from an elevated track; Y v

Fig. 2l is an enlarged sectional view through one" of the hangers;

Fig. 3 is a transverse sectional kview taken on line 3-3 of Fig. 2, and

Fig. 4 is a similar sectional View taken on line 4 4 of Fig. 2.

`The door opening 1 is confined by the two uprights or door j ambs 2, the upper ends of Z-proiile.

which are connected by the track supporting beam 3. The upper surface of this beam supports a track preferably formed of a casting or rolled metal bar of ysubstantially This track velement comprises a horizontal flange 4 spaced byv a vertical web 5 from the flanges 6 and 7, which are secured in some suitable way to the top and rear surface of the beamv 3.

The door 8 is equipped near its top with A'straps 10 which arev fastened to the doorand which are bent rearwardly at 1.3, and then downwardly at V11, the last named portion v-`specification of Letters JOHN J. nnxnorn, nncnasnnirnrE-orcnreaeog-i1gniv "1s f theitrack element.. `rThe Ifront .parti ofthe;l

strap maybe reinforced b y a suitable corrngati onasfindicatedat 12.V I. n;

. The carriage 9 is located rbetween the 10- and the back;plate=;11, and ,includes two similar lcastings each consisting ofv a wall 13, an upper track 14, extending circumferentiallyof the wall, anda lower track 15,

both of these track portions of each casting projecting'inwardly towards the other casting. The spaces between the projections 14 and 15, and the projection 15and the up-perl surface of the' track 4 serves as a race rfor the anti-friction rollers 17. From 3 and 4 itwill be noted that the path of these anti-friction rollers is approximately ellipticalas it is confined by the circumferential projection 14 and turns about the ends of the projection 15.l YThe spaces for these rollers are slightly larger than the diameter of the rollers, and the rollers in the lower track will vplace themselves atan angle Vto the 'upper surface of the track portion 4, as indi-- cated in Fig. 2, because the inner faces of the casting 13 are undercut in their lower parts. The two sets of rollers are held at a distance from each otherl by spacer castings 20 which are supported on the projection 15 and which are provided with recesses 21 to receivel journal pins 22 projecting from the rollers. The castings 13 are secured between the strap portions by bolts 23a-extendingthrough ears 24 outside the path of the ro 1ers.

Owin .tothe inclined position of the-Vrollers whi e in; engagement with the track. 4,

the contact'a'rea `between track and rollers (is greatly reduced and the possibility of bindingthe hanger thereby is excluded. It also assures an even wear on thelsurface of the rollers,- The entireitrack may be covered byV a` guard plate 25 which isfastened in a'suitable way above the door. 'f Y Claims.g '1 j* n j l 1. A.y door. hanger, comprising infcombination a strap secured to the door and projecting above the same,l castings secured to the strap, said castings facing each, other, rollers supported by ysaid 'castin s, a flat track surface on which some of t e rollers run, and meansfsecured between'the castings for separating the rollers into two sets and p ermitting angular positioningv of the rollers engaging said track, surface.

said front and rear portion, spacing members Vinserted between the two castings, a. metal bar presenting a flat surface upwardly above the door, and a plurality` of setsof rollers, said castings being provided with channels which bythe fiat surface of the bar are complemented to elliptical channels,lthe rollers travelling in said elliptical channels.

3. In 'combination with a' door hanger having a strap fastened to the door, atrack element presenting a flat surface upwardly,

a carriage secured to the strap, and Vrollers rotatably mounted 1n said carnage, the carriage being provided with inclined Wall portions' adapted to place the rollers which are in engagement With the track in angular position Wit-h respect to the track.
